Abstract： Objective This study was designed to compare the central and peripheral blood pressure changes before and after treadmill stress test among the aircrew and the non-aircrew, to examine the regularity of the changes in blood pressures of the aircrew and the effect of long term physical exercise on their vascular health, and to explore the blood pressure management and the value of central arterial blood pressure in the physical fitness assessment among the aircrew. Methods After collecting the medical history and recording the general information, the subjects were informed and asked to sign the informed consent form. The subjects were allowed to rest on examination table for 10 minutes before the blood pressure measurement. The peripheral blood pressure at the left brachial artery was measured with mercury sphygmomanometer, while the central arterial blood pressure was measured with a noninvasive aortic pulse wave analyzer. The subjects were asked to undergo the treadmill stress test until the target heart rates were reached. The subjects were allowed to lie on the examination table for six minutes before having their ECG and central arterial blood pressure examined. Results Among the aircrew, there were significant changes in peripheral arterial systolic blood pressure(SBP) and diastolic blood pressure (DBP) before and after the treadmill stress test (P<0.05). However, there were no significant changes in the central systolic blood pressure (CSBP) and central diastolic blood pressure (CDBP) before and after the treadmill stress test (P>0.05). Among the non-aircrew, there were no significant changes in peripheral arterial systolic blood pressure and diastolic blood pressure before and after the treadmill stress test (P>0.05). However, there was significant change in the central systolic blood pressure (CSBP) before and after the treadmill stress test (P<0.05), while there was no significant change in the central diastolic blood pressure (CDBP) before and after the treadmill stress test (P>0.05). Conclusions ①For the aircrew, the peripheral blood pressure changed significantly after the treadmill stress test, while the central arterial blood pressure was relatively stable. ②The effect of heart rate was significant on the peripheral blood pressure of the aircrew, but not significant on the peripheral blood pressure of the non-aircrew. On the contrary, the effect of heart rate was significant on the central blood pressure of the non-aircrew, but not significant on the central blood pressure of the aircrew. ③There was significant difference between the peripheral and central blood pressures (P=0.000). ④Long term physical exercise was beneficial to the vascular health of the aircrew. ⑤The change in peripheral blood pressure after treadmill stress test was smaller among the non-aircrew than that among the aircrew, while the change in central blood pressure after treadmill stress test was larger among the non-aircrew than that among the aircrew. Among the subjects, when there was no difference in peripheral blood pressure, there was significant difference in central arterial systolic blood pressure. ⑥Comparing with peripheral arterial blood pressure, non-invasive central arterial blood pressure was more stable, accurate and sensitive. ⑦ Non-invasive central arterial pressure measurement was very valuable to the diagnosis and management of hypertension among the aircrew.
